[Openmp-dev] testsuite script error

Thu May 14 20:19:19 PDT 2015

Hi Millad

Thanks for your answer, now I see what is happening.

However, please correct me if I am saying something wrong, I see that
these .ll files are generated by the Makefile in the testsuite/bin/
directory.
When I run "make test" in runtime, I get the following errors at the end,
after all tests have been compiled and run:

Makefile:19: recipe for target 'c/orph_ctest_omp_parallel_default' failed
make[2]: *** [c/orph_ctest_omp_parallel_default] Error 1
In file included from c/test_omp_get_wtick.c:4:
c/omp_testsuite.h:11:10: fatal error: 'omp.h' file not found
#include <omp.h>
         ^
1 error generated.

and similar..

I guess this is because the setting of the include path is not working (at
least on my machine). What is the right place to fix it?
testsuite/bin/Makefile? Should I fix it by hand before running make test
(in the sense that right now "make test" seems to do all the work for me)?

Also, running "make test" in runtime/ fills up my testsuite/ directory
with .log files. Is this expected? Incidentally, the .log files for
orphaned tests seem to be failing a lot (if not them all).

Thanks and apologies if I am missing some of the point

Hi Carlo,

I am responding on behalf of Sunita.

The "make test" command in the runtime folder does not only do the "make
ctest". The "make ctest" here actually tries to generate the LL files. And,
these LL files are consumed afterwards by llvm-lit command to see whether
the test is passed or not. So, "make test" command is not solely "make
ctest" and the test part happens with another command. We did provide this
rule, "make test", to make your life easier.
The peace of code that you mentioned is actually generating the LL files.

At first, we proposed to put the testing rule (make test) in the testsuite.
However, it was rejected. So, we tried to include it in the runtime folder
for sake of OpenMP testers.

And make -j: Simply, it tries to build a package with multiple jobs in
parallel in order to speedup building. For example, with (make -j 8), we
are trying to speedup the build process with 8 jobs (threads) in parallel.
If the number is not provided, like "make -j", then there is no limit to
number jobs and it tries to run it with as many as possible.

Bests Regards,
Millad Ghane

  Hi

  After recent commits, I am now able to compile libiomp5.so and use it in
  the tests.
  I noticed that the makefile in the runtime directory ultimately calls
  "make ctest" in the testsuite directory.

  If I do this manually "make ctest" inside testsuite after having fixed
  the Makefile (again, in testuite), all selected tests are run and
  verified, but at the end I see this:

  cd bin/; make -j
  make[1]: Entering directory
  '/gsa/yktgsa-p6/05/llvm-coral-build/repos/ppc64le/libiomp/testsuite/bin'
  clang -fopenmp -S -emit-llvm   c/test_omp_sections_reduction.c -o
  c/test_omp_sections_reduction.ll
  clang -fopenmp -S -emit-llvm   c/orph_ctest_omp_lock.c -o
  c/orph_ctest_omp_lock.ll
  clang -fopenmp -S -emit-llvm   c/orph_ctest_omp_parallel_if.c -o
  c/orph_ctest_omp_parallel_if.ll

  ....more similar commands leading to errors..

  Maybe I should not use the makefile in the testsuite directory, but
  apparently that is what the "make test" command does when run from the
  runtime directory.

  Do you have any clues about the meaning of that "make -j" command? Why is
  it there and what is the intended for?
  Maybe I am using a wrong repo for updating my local copy..

  Thanks

  Hi Carlo

  If you could simply use 'make test' from openmp/runtime folder, that is
  all that is needed.

  Sorry if the 2 READMEs are creating a confusion.

  Please drop us a note, if you have further issues.

  Thanks

        Hi all

        After fetching the latest version of the library from here:

        origin http://llvm.org/git/openmp.git (fetch)

        I started seeing the following error when I run "make ctest" in the
        testsuite directory:

        Testing for "has_openmp":
        Generating sources ..........Could not open the sourcefile for the
        main program ompts_standaloneProc.c at ./template_parser_c.pl line
        51.
        Could not open the sourcefile for the main program
        ompts_standaloneProc.c at ./template_parser_c.pl line 51.
        ERROR: Generation of sourcecode for the test failed.
        ERROR: Generation of sourcecode for the crosstest failed.
        .... failed

        for all tests. This happens equally on an Intel machine and a
        PCC64LE one.

        What am I doing wrong?

        Thanks
